Almost all nutural number seems to become palindromic
after several iteration of addition with reverse order of itself.
(I say this as "Additive Palindromicness of Natural Numbers".)
For example, in case of 76,
76 + 67 = 143
143 + 341 = 484
after 2 iterations, 76 becomes palindromic.
Following problems are still unsolved.
